Questions
Polar and Brex, answered
What can start an automation from Polar?
Any of Polar's 21 triggers in the catalog, including Benefit Created, Benefit Updated, Checkout Created and Checkout Updated. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Brex when something happens in Polar?
Any of Brex's 27 actions, including Create Department, Create Location, Create User and Create Vendor. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Brex to Polar?
Brex has no triggers in the catalog today, so automations start in Polar. If you need the other direction, ask: your agent reads Brex's API documentation and adds it.
Do I have to build a connector for Polar or Brex?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Polar and Brex without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
